BICYCLE.

SPECIFICAIION formng part of Letters Patent No. 669,201, dated Match 5, 1901.

Application filed September 23, 1899. serial No. 731,467- (No modal.)

T0 ztll wlw1n it may concern:

Be it known that I, JOHN G. IIEHR, of the cityof New York,borough ofBrooklyn,county of Kings, and State of NewYork, have invented certain new and useful Improvements in Bioyoles, of which the following is a full, clear, and exact specification, reference being had to the accompanying drawings, wherein Figure 1 is an elevation of my improved bicycle, and Fig. 2 is an enlarged detail view of the handlebar and steering-post.

Similar numerals of reference indicate corresponding parts in both views of the draw- 1ngs.

My invention relates to vehicles adapted to be propelled by pedaling of the rider; and it consists of the hereinafterdescribed improvemonts in the construction of such vehicles.

The construction of my improved vehicle is described With referenoe t0 a bicycle, as shown in the drawings. The saine is, however, applicable to tricycles and other similar vehicles, requiring only such slight modification in the construction of the frame as the number and arrangement of the wheels may requ1re.

The frame of the bicycle consists of forks 1 and 2, posts 3 and 4, and braces 5 and 6. The stem of fork 1 is snugly fitted in sleeve 7, resting on fiange 8, and is he1d therein by head 9. Braces 5 and 6 are welded or soldered to sleeve 7, to the stem of fork 2, and to post 3, respectively, as shown in the drawings. Post 4 is integral With sleeve 10, which is welded or soldered t0 brace 5 and is joined by brace 11 to brace 5.

Post 3 is mounted by means of sleeve 12 on the stem of fork 2 and supportcd by brace 5, which is integral With sleeve 13. The handle bar post 17 is set in post 3, and handlebar 18 is adjustably secured thereto. The handle-bar is supported by braces 19, integral with or secured t0 ring 20, which is snugly fitted upon post 3, and the collar 20 serving as bearing for same.

Post 4 is hollow, and saddle-post 14 is snugly fitted therein. Saddle-post 14 is adjustable with reference to post 4 and is secured in position by set-screw 15. Saddle 16 is adjustably monnted thereon and secured thereto in the usual manner. Handle-bar 18 is shaped in the form of a back-rest for the rider, and its termini are elongated to form supports for the elbows and the arms of the rider.

Back-rest 21, corresponding in shape with the handle-bar 18, is set upon it and connected thereto loy posts 22. If my improved vehicle is built in the form of a bicycle, as shown in the drawings, there is only one wheel in each of the forks 1 and 2. Of these the front wheel serves as a driving and steering wheel, while both wheels support equally the wighi of the Vehicle and of the body of the rider.

If the vehicle is built in the form of a tricyole, two wheels are placed in the rear, as

is usually done in tricycles, and then fork 2 is mounted on their commou axle.

The steering of the vehiele is accom plished by the handle-bar through the following meehanism: A rack 23 is affixed to the apex of the handle-bar 18 and engages with pinion 24, rigidly secured to post 25. This post is mounted in bearings 26, secured by set-screws to post 3, and on its lower end is mounted a sprocket or rope wheel 27. A chain or rope 28 is stretched over this sprocket or rope wheel 27 and sprocket or rope flange 29, provided on the stem cf fork 1. This chain or rope 28 is preferably crossed to bring the turns of the wheel in agreement With the turns of the handle-bar.

The vehicle is propelled by the pedaling of the rider, whose feet work on pedals 31, op erating the propolling-gear arranged in connection with axle 32 and within the spokes of the front wheel.

I claim as my invention and desire to secure by Letters Patentl. A vehicle comprising a frame composed of two forks joined together by braoes as herein sh0wn and described and of two posts,

a saddle-post and a back post, joined to the forks and to the braces; whe6ls rotatably mounted in bearings set in the ends of the forks, a back-rest set movably on the back post and provided with extensions for supporting the arms of the rider; a rack affixed to the back-rest, a spindle set parallel to the back post and journaled in bearings aiixed thereto; a pinion set on the upper end of the spindle and engaging with the rack, a sprocket-wheel set on the lower end of the spindle, a sproeket-fiange Set; on the stem o'f forkS, back ret set: m0vably on the back the forward fork, a chain Strett3hed over the pd3t and p'rox' ided Wit;h extensions for supsproeket-wheel and the sprocket-flange of the 1 porbing the arms of the rider, means for transfork-stem; a driving-wheel set in the forward l mitting bhe motion of the back-rest to the stem fork and means for propelling t h yehicle off the forward fork ;adriving-wheel set in mounted on the axle of th drviDg-Wheel. the fdrwrd fdrk and fnans for propelling 2.
